Jacques Heath Futrelle (April 9, 1875 – April 15, 1912) was an American journalist and mystery writer. He is best known for writing short detective stories featuring Professor Augustus S. F. X. Van Dusen, also known as "The Thinking Machine" for his application of logic to any and all situations. Futrelle died in the sinking of the RMS Titanic.

Futrelle left the Boston American in 1906 to focus his attention on writing novels. He had a harbor-view house built in Scituate, Massachusetts, which he called "Stepping Stones", and spent most of his time there until his death in 1912.[1]

His last work, My Lady's Garter, was published posthumously in 1912. Futrelle's widow inscribed in the book, "To the heroes of the Titanic, I dedicate this my husband's book", under a photo of her late husband.[2]

Returning from Europe aboard the RMS Titanic, Futrelle, a first-class passenger, refused to board a lifeboat, insisting his wife board instead, to the point of forcing her in. His wife remembered the last she saw of him: he was smoking a cigarette on deck with John Jacob Astor IV. Futrelle perished in the Atlantic, and his body was never found.[4][5]

On 29 July 1912, Futrelle's mother, Linnie Futrelle, died in her Georgia home; her death was attributed to grief over her son's death. [6]
